Acids and Bases

Solvent Effects on Acid-Base Strength

By: Brian G. Cox

Acids and bases are ubiquitous in chemistry. Our understanding of them, however, is dominated by their behaviour in water. Transfer to non-aqueous solvents leads to profound changes in acid-base strengths and to the rates and equilibria of many processes: for example, synthetic reactions involving acids, bases and nucleophiles; isolation of pharmaceutical actives through salt formation; formation of zwitter- ions in amino acids; and chromatographic separation of substrates. This book seeks to enhance our understanding of acids and bases by reviewing and analysing their behaviour in non-aqueous solvents. The behaviour is related where possible to that in water, but correlations and contrasts between solvents are also presented. Fundamental background material is provided in the initial chapters: quantitative aspects of acid-base equilibria, including definitions and relationships between solution pH and species distribution; the influence of molecular structure on acid strengths; and acidity in aqueous solution. Solvent properties are reviewed, along with the magnitude of the interaction energies of solvent molecules with (especially) ions; the ability of solvents to participate in hydrogen bonding and to accept or donate electron pairs is seen to be crucial. Experimental methods for determining dissociation constants are described in detail. In the remaining chapters, dissociation constants of a wide range of acids in three distinct classes of solvents are discussed: protic solvents, such as alcohols, which are strong hydrogen-bond donors; basic, polar aprotic solvents, such as dimethylformamide; and low-basicity and low polarity solvents, such as acetonitrile and tetrahydrofuran. Dissociation constants of individual acids vary over more than 20 orders of magnitude among the solvents, and there is a strong differentiation between the response of neutral and charged acids to solvent change. Ion-pairing and hydrogen-bonding equilibria, such as between phenol and phenoxide ions, play an increasingly important role as the solvent polarity decreases, and their influence on acid-base equilibria and salt formation is described.

An Introduction to Splines for Use in Computer Graphics and Geometric Modeling

By: Richard H. Bartels,John C. Beatty,Brian A. Barsky

As the field of computer graphics develops, techniques for modeling complex curves and surfaces are increasingly important. A major technique is the use of parametric splines in which a curve is defined by piecing together a succession of curve segments, and surfaces are defined by stitching together a mosaic of surface patches. An Introduction to Splines for Use in Computer Graphics and Geometric Modeling discusses the use of splines from the point of view of the computer scientist. Assuming only a background in beginning calculus, the authors present the material using many examples and illustrations with the goal of building the reader's intuition. Based on courses given at the University of California, Berkeley, and the University of Waterloo, as well as numerous ACM Siggraph tutorials, the book includes the most recent advances in computer-aided geometric modeling and design to make spline modeling techniques generally accessible to the computer graphics and geometric modeling communities.

Lead in Soil

Recommended Guidelines

By: Bobby G. Wixson,Brian E. Davies

Until the publication of this new book there had been a lack of well-founded guidelines for evaluating concentrations of lead in soil and its relationship to human health. Thus, much confusion has existed among regulatory agencies, industries, public health officials, and the medical community about the evaluation and remedying of lead-contaminated soils. Lead in Soil: Recommended Guidelines represents the combined efforts of a multi-disciplinary international task force from the Society for Environmental Geochemistry and Health (SEGH) whose members are experts in the fields of lead pollution and toxicology. It provides an international consensus concerning environmental lead and blood lead-especially in children. The task force evaluated the evidence and made recommendations for guidelines to appraise lead concentration. It also studied the influence of soil and other sources of lead on blood lead concentrations. A model was prepared that allows the user to select appropriate target levels of blood lead while allowing for a variety of environmental situations or regulatory criteria.

The Battle of the Fields

Rural Community and Authority in Britain During the Second World War

By: Brian Short

This book will appeal not only to historians and geographers, but to many who maintain a deep interest in the British countryside and its past, and to those who continue to share a fascination for the Second World War, in particular the 'home front'. The Battle of the Fields tells the story of rural community and authority in Britain during the Second World War by looking at the County War Agricultural Executive Committees. From 1939 they were imbued with powers to transform British farming to combat the loss of food imports caused by German naval activity and initial European mainland successes. Their powers were sweeping and draconian. When fully exercised against recalcitrant farmers, dispossession in part or whole could and did result. This book includes the most detailed analysis of these dispossessions including the tragic case of Ray Walden, the Hampshire farmer who was killed by police after refusing to leave hisfarmhouse in 1940. The committees were deemed successful by Whitehall as harbingers of modernity: mechanization, draining, artificial fertilizers, reclamation of heaths, marshes and woodlands. We now deplore some of these changes but Britain did not starve, in large part thanks to their efforts. This book will appeal not only to historians and geographers, but to many who maintain a deep interest in the British countryside and its past, and tothose who continue to share a fascination for the Second World War, in particular the "home front". It will also demonstrate to all who are anxious about food security in the modern age how this question was dealt with 70 years ago. BRIAN SHORT is Emeritus Professor of Historical Geography at the University of Sussex, and formerly Dean of School and Head of the Department of Geography.
